Abstract

The invention relates to a safety device for a vehicle baby chair. The device of the invention comprises: a safety belt comprising (i) two adjustable straps (2) fastened to a bifurcated strap (6) with a buckle (5), and (ii) for tensioning said straps (2) means (12). The invention is characterized in that the lower ends (1) of the tethers (2) extend through the chair (7) at (8) and are coupled together underneath them at (10), thereby forming a tensioning device (12) and A strap (11) extending beyond the front of the seat (9) of the chair. In addition, the lower end (1) of the tether (2) passes through the assembly (14) of guiding elements before being coupled together. Adjustment of the straps (2) is performed using a fixing device (18) provided on the rear surface of the backrest (19) of the chair.

Description

Safety devices for baby chairs in vehicles

technical field

The invention relates to a safety device for a baby chair suitable for a vehicle.

Background technique

Different types of such baby chairs are known, which comprise, in order to securely fasten the child to the seat, a fastening strap formed by two adjustable straps linked by buckles to the bifurcated bars, the straps The straps are interconnected at the rear of the backrest and thereby form a length that passes through the tensioner and extends beyond the front of the chair seat.

Contents of the invention

The purpose of the present invention is to improve these safety devices, which is achieved in such a way that the relative elasticity presented by the tethers is limited so that they are thus in a position in the event of a crash to better hold the child to the chair .

In order to achieve this elastic limitation, the overall length of said straps has been reduced, for which purpose it has been foreseen to perform their tensioning function at their lower end, which is guided through the buckle and extends through the chair so that it The undersides are joined together and thus form a strap that passes through the tensioner and extends beyond the front of the chair seat.

The lower ends of the tethers are coupled together with guide elements adapted to be arranged in mutually juxtaposed arrays at a central length before they are coupled together.

Adjustment of the straps is performed using fastening means provided on the rear surface of the chair back.

These and other features will become more apparent from the following detailed description, which can be more readily understood from the accompanying pages, showing practical embodiments cited by way of example only and not limiting the scope of the invention.

Description of drawings

In the attached picture:

Figures 1a and 1b illustrate, respectively, a cross-sectional view of a conventional safety device and a safety device which is the object of the present invention;

Figure 2 shows a front view of a baby chair provided with relevant safety devices; and

Figure 3 illustrates a perspective view of a detail of a guide adapted to bring together the lower ends of the straps.

Detailed ways

According to Fig. 1a, conventional devices have their tethers (T) joined together at the rear and thus form a strap (C) extending at the rear of the chair and thus through the tensioner (Te), and the strap The end (E) of the strip extends beyond the front of the chair seat (S). At their lower ends, the tethers (T) are fitted to the buckles (H) and are fixed firmly at the lateral position (P) of the chair seat (S).

According to Figures 1b, 2 and 3, the safety device that is the object of the present invention is characterized in that the lower end of the tether (2) (1) extend through the chair (7) through an opening (8) provided at the rear of the side of the seat (9) of the chair and are coupled together at (10) below this, thereby forming The device (12) and its ends (13) extend beyond the strip (11) of the front of the seat (9) of the chair.

Before being coupled together, the lower ends (1) of the two tethers (2) pass through an assembly (14) of guide elements supported by a plate (16) firmly attached to the bottom of the seat (9) Supported rollers (15) are made which are adapted to guide said opposite ends (1) at a common, central length (17) joined to the strip (11).

The adjustment of the straps (2) is carried out by means of a fixing device (18) provided on the rear surface of the backrest (19) of the chair.

Because of the shorter length of the tether straps (2), their extension (X) (Fig. 1b) is reduced, thus protecting children in an improved manner.

The assembly ( 14 ) of the guiding means for their adjustment and the fixing means ( 18 ) arranged at the rear end of the strap can be implemented according to any other embodiment than those already described here.
